Sweet William Dianthus

This familiar biennial features large 4" clusters of 1/2" flowers on 18-24"stems. Blooms in June and thereafter, in lots of different colors from white through deep red. Reseeds itself vigorously. The 1936 Vicks Seed catalog describes Sweet William as a favorite of old-time gardens, so it has been around a century or more and remains a personal favorite.
